Question: A single-pass cross-flow heat exchanger is constructed using the circular fine surface designated as #CF-8.72(c), Fig. The dimensions of the heat exchanger on the face that exposes the fins are 0.6 m x 0.6 m (i.e., a square cross-section), while the dimensions on the face exposing the ends of the circular tubes are 0.6 m x 0.5 m. Air at 1 atm pressure and 1SoC flows into the finned side at a rate of 2 kg/s, while water at SO°C flows through the tubes at a rate of 5 kg/so The tube wall thickness is 0.5 mm. The construction material is copper. Determine the outlet temperatures of the two fluids and the pumping-power requirements for both.
